Hicks: Carrie Fisher has bipolar episode on cruise ship

Carrie Fisher was hospitalized after a bizarre performance on board a Caribbean cruise ship last week that her rep said was caused by bipolar disorder, according to TMZ.

The website displayed video of Fisher slurring a couple of off-key songs on board the Holland America Eurodam in the Caribbean. She had her dog on stage, which was apparently using the floor as its personal toilet while she sang.

I blame George Lucas, Hayden Christensen and Jar-Jar Binks. Who's with me?

TMZ said there were reports Fisher -- who was featured on the cruise as a "surprise" celebrity guest -- was drunk, but her rep said ,"There was a medical incident related to Carrie Fisher's bipolar disorder. She went to the hospital briefly to adjust her medication and is feeling much better now."

Fisher is a recovering drug addict who has publicly discussed her bipolar disorder. The rep says it's unclear if she will return to perform on the cruise ship.
